Some time back someone posted a link to a video showing a chap drilling
a hole in a thin brass bar in a lathe.
Iirc he used a chaser to make a cone-shaped cut in the end of the bar,
then used a drill held in his fingers to make the hole. It was a very
small lathe, probably a watchmaker's.
Anyone remember this, and have a link to the video?
Update, it's ”Drilling an Orifice on the Lathe.” but sadly it doesn't
seem to be available - there's a message on youtube saying it's a
private video, whatever that means.
Why I'm asking is it's an example of axis-following in drilling - the
drill follows the axis of rotation of the part (the part is rotated, not
the drill). Anyone have any similar links?
Another question, can a drill be "steered" and if so how?
Thanks,

--I remember that; I think it was called "picking the center" or
something similar; try searching that string?

Peter,
Probably not relevant to your needs, but oil well drillers do it all the
time, with a variety of means, limited only by the flexibility of the
drill pipe. See, for example:
http://www.glossary.oilfield.slb.com/Display.cfm?Term=directional%20drill
ing
but I'm sure a search would give more comprehensive expositions, with
pictures.
